Gas CYLINDER.

Application filed August 26, 1922. Serial No. 584,426.

To all whom it may concern:

Be it known that I,CHARLEs L. GULICK, a citizen of the United States, residing at Orange, in the county of Essex and State-of 5 New Jersey, have invented certain new and useful Improvements in Gas Cylinders, of

which the following is a specification.

Cylinders or bottles for the storage, trans port, and dispensing of liquids or gases are provided at their neck end with a valve which, in transport, is enclosed within a temporary cap or closure, and which otherwise is not enclosed'and .is therefore exposed to injury, as for example, when the cylinder is accidentally tilted.

- The principal objects'of my invention are to provide for housing the valve within the walls of the cylinder so as to protect it from injury and in order to isolate leakage of dangerous gases; and to provide a tell-tale for indicating such leakage.

The nature, characteristic features and scope of the invention will more readily be understood from the, following description taken in connection with the accompanying drawing forming a part hereof, and which is a sectional view ofa cylinder constructed in accordance with my .invention.

According to my invention, Iform a cyl- 3 inder 5, with a constricted or neck portion 6 intermediate the ends thereof, with the upper end 7 continued in the same diameter as the main portion 5, and at any rate of a diameter and length sufiicient to completely 85 house the valve 8. The valve 8 is detachably fitted to the neck portion as usual, and when the integral housing portion 7 is closed any leakage from the valve will be confined in the chamber afforded by the 40 housing In order to ensure isolation of such leakage, Iprefer to employ a cap or plug 9 which is threaded to engage the in:

ternally threaded portion of thehousing 7,

and which has a sealing flange 10which cooperates with a gasket 11, and .Withtheend wall of the housing to establish a gastight joint. It is desirable in thecase of hydrocyanic, ammonia, and other dangerous gases, to have some indication of they claim 1. A seamless drawn metal cylinder having its side walls depressed whereby it is divided into a main gas holding'portion and j housing-for the valve mechanism, and teln porary sealing means to form with the cylinder a chamber for'isolating leakage past the valve, said sealing means having provision for safely venting any leakage.

In testimony whereof I aflix my signature.

CHARLES GULICK.
